Find your trail in Loam and turn on alerts. Watch one network free. No account needed.
Tree cover, trail elevation and recent weather vary across the Puget Sound lowlands and Cascade foothills. Compare the actual network before driving. Destinations east of the Cascades appear separately because they belong to a different trip.
Across the 22 networks Loam tracks here, elevation spans 4,597 feet and canopy runs from 0 to 84 percent. These measurements describe representative network points, not the full elevation range of every trail. Compare the individual forecasts and check local reports before choosing a ride.
The useful unit here is the riding zone. Each one has its own exposure, elevation, and weather response.
Duthie is a forested bike park on the Sammamish Plateau. Tiger Mountain and Raging River have their own larger trail systems, while Tokul is on working forest land. Check each area's access and trail directions.
Cheasty, the Finn Hill area and Lord Hill are separate local riding choices. Their routes share space with other park users; follow the bike-designated trails and posted directions.
Black Diamond and Danville-Georgetown are neighboring open-space areas southeast of Seattle. Use local maps to plan the connections rather than treating a regional pin as a route.
Banner Forest and 360 Park are on the Kitsap Peninsula. Account for the crossing or drive when comparing them with an Eastside ride.
South Sound options range from Tacoma parks to Capitol Forest near Olympia. This is a broad travel area, not one connected trail network. Check the relevant park or forest map.
These mountain destinations sit apart from the lowland trail systems. Confirm summer operations, trail openings and any lift or pass requirements directly with the operator.
These are separate destinations east of the Cascades. They are not Seattle-area trailheads, and a west-side rain forecast does not describe their riding conditions.
Planning patterns, not opening dates. Live conditions and official access decide the day.
Lowland trails and higher forest rides can be in different stages of drying or thawing. Watch for soft tread and storm damage.
Dry stretches can leave loose surfaces even in the forest. Check fire restrictions and mountain bike park operations.
Rain returns as daylight shortens. Compare the recent rain and current conditions at the trail rather than relying on weather in Seattle.
Cold pockets, storms and snow can limit higher rides. A lowland forecast does not establish access at Snoqualmie Pass.
Check DNR alerts for Tiger Mountain and Raging River, King County's Duthie information and Evergreen's local trail guide. Forestry operations, trail directions and seasonal park schedules can override a rideable model.

Trail work around Seattle & Snoqualmie is done by Evergreen Mountain Bike Alliance and Friends of Capitol Forest. Support your local builders.
22 of 22 networks around Seattle & Snoqualmie currently have a PRIME or DUSTY verdict, meaning rideable conditions. Check the network page for details and closure notices.
Rideable options around Seattle & Snoqualmie include #2 Canyon (PRIME, firm, rideable conditions), 360 Park (PRIME, firm, rideable conditions) and Banner Forest (PRIME, firm, rideable conditions).
Sometimes, but the answer depends on the trail and how much rain it received. Compare the current network estimates and check official alerts. Turn back if your tires leave ruts or standing water blocks the tread.
They are separate systems near the Eastside and Snoqualmie corridor. Duthie is a purpose-built bike park; Tiger and Raging River are working state forests. Check each system's routes and permitted uses.
They are farther destinations in Loam's current regional coverage. The map places them in their own area so they are not mistaken for nearby Seattle trailheads.
Loam updates condition estimates hourly. Each network page shows when its estimate was last updated.
Loam uses recent rain, soil, slope, slope direction, tree cover, and current weather to estimate how wet the ground is. These are estimates, not rider reports. Official closures take priority. See how the model works.
